    Strange Surefire U2 problem with ring

    I think I can rule out the tailcap: Screwed down all the way the light works on the all the levels it has; unscrew it about a half turn and the light goes off no matter what level chosen on the ring.

    3 levels (lowest, next and then maybe level 4) with the 123s and nothing at all with the Pila.

    Thanks for the advice on the magnet. I don't seem to have the 4 legs in the tailcap you and others have described. Instead there are three copper tabs at the rear end of the tailcap that make contact with the battery tube when screwed in all the way.

    Mine is an old style U2; but no plastic insert; tight fit for Pila 600s; 18650 out of the question.

    Strange Surefire U2 problem with ring

    Maybe I have a bad batch of new Duracells but I never got anything higher than level-3-4. The dropoff was WAY fast with the Surefires. No more than 5 to 10 mins max at the high setting on the new Surefires. Anyone would have mentioned this reviewing the light because it would render it...

    Strange Surefire U2 problem with ring

    Some clarification: The AW 17670 (unprotected) never made contact as they are too short. The Pila 600S is a protected cell that many members here have had lots of success with. I have read of no prior reports of people having problems with either unprotected 17670's (presumably with a spacer)...

    These were new Surefires and new Duracells from Flashlightz.com. No rechargeable RCR123s, just the 17670's and Pilas tried as well. The Pilas workedgreat but were a tight fit. The 17670s fit well but need a magnet spacer.

    Strange Surefire U2 problem with ring

    I just received a brand new U2 today. It worked perfectly. 6 evenly spaced gradations of light. Tried my new AW17670 batteries- Nothing. They seem too short. Tried the Pila 600S- very tight fit but it worked great. Swapped back and forth a few times trying to get the AW17670's to work...
